Abstract:This entry presents the most commonly used formulations of robust stability and robust H 1 performance for linear systems with highly structured, linear, time-invariant uncertainty. The structured singular value function ( ) is specifically defined for this purpose, involving a problemspecific set, called the uncertainty set. With the uncertainty set chosen, is a real-valued function defined on complex matrices of a fixed dimension. A few key properties are easily derived from the definition and then applied t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
